Topic: Simple to build isolation transformer that consumes less power than it gives out (Read 261605 times)

The problem is that nobody so far replicated original circuit. Apparently all commercial transformers are build to eliminate our desired effect by purpose. Most I have found is quite low resistance on primary, mostly 40 ohms for 40-50VA trafos. Now , building own version is very tedious but I try my best. According to my theory every transformer should be almost 200% efficient in optimal circumstances. Simply saying electric field is what is pushing electrons but magnetic field interactions lag it and disallow light speed. Lenz law for dummies Anyway, I will try but my tools and materials are very limited. For example I had a lot of 20 stranded litz like wire from one of synchronization coil from TV but it is in shorter pieces so I don't expect to be able to wind perfectly symmetrical transformer :-(

Would be better if you can post schematics or pictures of you current experiements.

Back to winding "trees" 4 coils times 20 strands and join in series ... ooouch

I tried parallel cap and I was able to find resonance point when load was off. But when load was connected resonance was destroyed and current limiter bulb begin to glow brightly while there was only little light in load. So tuned capacitor as I placed in the above picture does not work.

Next I doubled the amount of turns in the bifilar coil but it was not good either. I think thicker wire would work better because there would be more copper to collect juice and less ohmic resistance. I used 0.31 mm wire. Did not test this it as I don't have suitable wire. When frequency is increased impedance increases also and we could use thicker wire and less turns. It is enough to use as few turns as possible in the first coil so that it forms high impedance at intended frequency. Then make bifilar coil using enough turns to get desired output voltage. Or maybe yank it to kilovolt range and then put step down trafo as load.

I think I have now gone as far as I can go without any measurement instruments. Maybe someone can now continue with more experiments and contribute.

I built almost similar kind of device several months ago. I used three cores, primary went through 2 cores then secondaries were connected in bucking mode using third core. It was three similar toroidal trafos connected together, very simple setup. One secondary was shorted to itself and power was then taken from the other secondary. Also secondaries in parallel worked but it did not give out any more power. I got about COP 2, 100 watts in and 200 watts out. I was not happy with performance because parts costed 90 Euros + wire cost and I only got 100 watts extra. At that time I had working meter and I used toasters for testing. When I took power, power consumption went down. But when no power was taken there was power going through primary and that was not good. So I dumped the idea. Later on I realised that I could have had better COP by using bigger output core but did not bother to test it. I had three output cores but they were on different toroids. I should have combined several toroids into one core instead. If someone has three 1:1 trafos laying around I can put a diagram of the setup here, one trafo preferrably bigger. The setup caused high frequency oscillations when not connected, cores rattled. I measured random fluctuation between 500 and 2 kHz. When power was taken this stopped. At certain coil length combinations this oscillation was not random and it was fixed to certain frequency, I recall meter showed 2222 Hz.

Anyway, trafo setup used here is better because it does not use input power at all even when load is taken.

Even though Peter does claim OU, it's obviously raising the output voltage at the sparc gap . The sparc gap itself is a small capacitor. The Output Energy to the cap is squared to the voltage.Put another diode or fwbr in series with a HV-Cap instead of the sparc gap. Now you can calculate In and Output Energy. I don't have a clue why putting the HV diode from LV+ to HV+ on the ignition coil has this effect. But experiments of tiger2007 with triodes to use an avalanche effect are similar to this.http://cyberenergy.ru/generator-kapanadze/ustanovka-tiger-t19-120.htmlPeters setup would have a benefit on all electrolyzers.

Even though Peter does claim OU, it's obviously raising the output voltage at the sparc gap . The sparc gap itself is a small capacitor. The Output Energy to the cap is squared to the voltage.

When there is half wave discharge and you provide diode to short BEMF rising then there are additional processes are going on in coil. First it will make half-wave resonant oscillation then voltage amplitude rises to maximum and there you get better sparks... This phenomenon is not used much and in case if you make circuit like this, it should start saving energy for transformers when using DC half-wave oscillators. Additionaly when there is capacitor charge/discharge there is explosive energy involved.

Sorry I don't have camera to make any videos/pictures. If you have gear to do high frequency tests then you can make the video if it does not work. It will not take much time to wind 11 and 140 turns around ferrite and connect them as shown. This will stepup the voltage so you can drive it using 5 volts and get for example 220 volts at load. The number of turns in the shorter coil is determined by the drive frequency and permeability of the core, enough turns that no power gets through when using just this one coil. I think tuned parallel cap would work also when placed next to shorter coil, but haven't tested. Worth a try anyway.

At the moment I am trying to figure out why watt meter shows inconsistent readings compared to testing directly using power from grid. I think I need to make tuned tank circuit in trafo 1 and then connect second trafo using two coils, the original setup. I try to drive first trafo using square pulses, bifilar primary coil connected from end. This should raise the resonant frequency higher and tank circuit should provide longer lasting ring because coil is bifilar. I check if diodes have any effect, most likely one is needed so that tank rings the coil and not the driver. When resonance is found, I change on/off ratio.

If this two trafo test is successful, then I would try using lower permeability core in first trafo and higher in second. This should provide feedback to source which is higher than the drive and voltage would accumulate in the tank cap as the feedback is in phase with source. GDT parallel to cap provide overload protection in first trafo and thing should then run by itself, or provide better output. I have a tiny ferrite which I could perhaps use for testing, got it from broken printer. There is maybe not enough room for windings though.

Testing might take some time, this is why I put here in advance what I am going to test, maybe someone could try the same things too.

I had some tests on your supposed project. The reviews are in your favour as efficiency of transformer seemed to be 99%. I'll try to highlight your idea in regional electrical institutes so as to develop it in more efficient way._____________________manuka honey for skin care.

Can you describe what kind of trafos you used for testing ? What was the impedance of your coils and power levels you used ?

This setup splits the voltage, so a 1:2 ratio could be used to get back to original voltage level. My test trafos started to use power then, but maybe this was just because of my setup. It is worth a try anyway. When coils are uneven, shorter coil gives more amps than volts and longer coil gives less amps and more volts.

Could someone explain me what is idle current on primary side of transformer dependent on ? Resistance of wire is one known factor of course, what about core size or number of turns ? I found it interesting that the smaller transformer the smaller idle current but it may be related to resistance of windings when number of turns required is high because of small iron core. Hence the bigger transformer the bigger core and less turns but also bigger idle current :-( Somehow producers of commercial transformers choose the minimum of turns on primary side which makes our testing very hard due to high idle current

"Now look at the picture, the second trafo is connected so that as current in one coil goes from left to right, it creates current in the second coil from right to left. Then I feed both currents to load from the same side. When load is connected current on primary side rises for a moment and then it returns back to same level as before."

Jack , would you be so kind to draw schematic with coloured arrows explaining how you envisioned currents in this second transformer ? Why you think that current flowing from the upper coil do not pass into load directly but rather flow into the lower coil of this second transformer (is this what you state ? I can only imagine this case when the currents both from the secondary of first trafo (original current) and the current generated inside lower coil of second transformer can go to the load from the same side (left side). Really your help is highly important here. As I finally made a few trafos I will try to help yet I'm not skilled .I'll try to perform tests if circuit could work with my not so pure sine wave inverter Powerware 5115. Later maybe using 20W sound amplifier if possible. I really want to understand this effect which is the real key to OU.

What happens is my speculation, it might not be correct so it does not make sense to draw diagram about it. There is also an option that watt meter gives me wrong results because load is inductive. Current limiter bulb might give wrong result also, current is going through it but voltage is not high enough to affect light brightness, so this should be measured using proper meter.

If you can create the two bulb scenario where limiter bulb has no light but output bulb has light, then measure current that come in and then voltage across L and N, that is between L and both sides of the limiter bulb. If this voltage is close to 0 volts, then power is not being used as much though there is current going, is this correct ? If possible, try to measure using both setups.Earlier measurement have shown that voltage drop over limiter bulb is only few volts, what does it mean ? Obviously limiter bulb is not using power, but does it mean that the entire circuit is not using any power from source ?

As you see, there are still questions that should be answered but I don't have proper instruments. I hope you, or someone else can clarify in detail what is going on in this little circuit when using coils that have high enough impedance. Tank circuit works too so it is not necessary to wind lots of wire for the coils.

I have made setup from four 10W 230V to 15V transformers.I recreated two bulbs scenario, but there is no effect as you described. I proved two things. On idle I have 15,5mA running through primary of first trafo with the help of two capacitors in parallel to primary. When I connected wrongly the second trafo the limiter bulb 25W/230V was lit and current consumption rised to over 100mA before I disconnected it quickly. When I reversed connection the current used on primary side on first transformer was exactly as you described : around 16,2mA or just a bit more then in idle state (I think I could balance it down to idle by adding additional capacitor).Next I measured voltage on output and it was 115V exactly half of the input (or output of first trafo). Autotransformer theory fully confirmed.

With load of 1W LED light it looked like not consuming more then on idle, but what is 1W, anyway ? I changed load to 7W 230W incandescent bulb and unfortunately noticed rise of current in primary of first trafo from 16 to 25,7mA. The main effect you stated is not here : the blink of limiter bulb and then fall of primary current back to idle state !!! I really wanted to see it ! Jack, where is the secret please ?

I measured 1.6V AC across limiter bulb on idle state , which rised to 3V when load was powered. Between L and each side of limiter bulb (which is connected to N side like you described (L-trafo primary-bulb-N)) I measured fluctuating 238 to 243 V AC so the difference was not visible at first.

There must be something different in my setup , because I can't replicate the effect. Maybe those capacitors across primary of first trafo ? Or maybe the resistance of load bulb tested (7W,15W and 25W 230V) ?

One more note - if I shorted the wires where load is connected I've got almost 200mA and bight light of limiter bulb (of course I shut down it immediately).I think for any OU setup I should have no effect on source while testing this way..
